TO ALL WHOM IT MAY CONCERN: i

Be it known that I, E. SHOPBELL, `oi` Ashland, in the county of Ashland, and State of'Ghio', have invented certain new and useful improvements in Lifting-Jacks;l and I do hereby declare that the following is a fulll and complete description of the saine, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is a side view of 1the lifting-jack.

Figure 2 is a vertical section.

Like letters of reference refer to` like4 parts in the different views: i

In the drawings, A, tig. 1, is a tubular standard, in which the slide B is moved up and down by means ot the lever C and pawls D. This slide is furnished with a rack on each side, as shown in iig. 2, the lever C formingl an arm on each side of the standard, to which it is pivoted. The pawls D, above referred to, are pivoted, one on each side oi' the slide, to the lever C, as shown, the upper ends catching in the rack of the slide. These pawls are held in the rack by means of a spring band, B', passing around them. Pivoted to the side of the standard, at a, is a cam, E. b b are points or pins, extending, from the pawls, as represented in iig. 1. Y

When the jack is to be used, it is placed so that the cap on the end of the slide comes under the axle of the Wheel. Then by moving the lever up and down, thus working the pnwls in the racks of the slide, itis 4caused to rise, thus raising the wheel from the ground. As the lever is pushed down, one of the pawls raises the slide, vvhile the other moves down to catch into thc notch below. Thus one'pawl rises as the other one is moved down, each one alternately raising the slide. When it isdesired to lower the slide, the cam E is turned, so

that the ends will press against the pins b, referred to, and thus pushing the pawls out of the rack of said slide and allowing it to drop back into said standard.

What I c laim as my improvement, and desire to secure by Letters Patent, is

The perforated tubular standard A, with the `pivoted lever O and cam E, in combination with the sliderack B, pawls D, and spring B', all arranged and operating conjointly, substantially as and for the purpose set forth.
